User involvement in New Service Development(NSD) has attracted the limelight as a good method, but we still lack an empirical analysis of the effectiveness of user involvement. In addition, positive and negative determinants of user involvement in NSD have not often been dealt with in past research, and this deficiency has been identified as a barrier to the effective utilization and diffusion of user involvement in NSD. To our knowledge, this is the first study to empirically investigate the degree of implementation of user involvement in NSD, the effectiveness of user involvement, and the utilization strategy in the digital content industry. First, we reveal that ordinary user involvement is more effective for NSP performance than lead users or business partner companies. Second, we empirically demonstrate that the effectiveness of involving lead user and ordinary user in NSP is different according to the new service type and service development stage. Based on the results of our analyses, we suggest some strategic directions for the companies who want to newly adopt or improve their current level of user involvement in NSD. We expect that the implications of this study will be utilized for efficient diffusion of user involvement in NSD and will eventually contribute to tangible achievements for companies in the digital content industry.

Recently, game companies are having difficulties in exactly figuring out the right consumer groups for their games. To solve this problem, a system algorithm which recommends user-customized games based on the user information entered has been proposed in this study. Game developers will be able to clearly determine the consumer group(s) of both on and off-line games through accumulated data while consumers can find the game they desire. It is expected that the gaming culture will advance further with the proposed algorithm.

근래에 들어 사용자를 중심으로 한 제품개발 전개 활발히 진행되어지고 있다. 사용자 중심의 디자인 중에서도 UI(User-Interface '이하 GUI')분야는 컴퓨터의 발전 속도에 의해 급속히 전파되고 있다. 하지만 디자인분야의 Ul는 GUI(Graphical User-Interface '이하GUI')분야에만 기형적 발전이 이루어지고 있는 것이다. (중략)

The multimedia documents becomes the most natural user interface for CSCW(Conputer Supported Cooperative Work) in distributed environment. The objective of this study is to propose a multimedia document architecture and to develop a system that can manage it well. The new architecture is for revisable documents and is the basic layer for hypermedia documents. A good document architecture for CSCW must support pointing, marking, and editing over a part of documents. The user views, version control, and full- content search are also desirable features. In this paper, we discuss the basic concept of a new document architecture for CSCW. We also present the user interfaces for spatio-temporal compositions of multimedia documents.

This paper reports results of a recent survey of 184 Information Technology(IT) development practitioners and 90 User Interface (UI)/usability practitioners. This survey covered a broad range of issues including the respondents' profile, current development environment, usability and user-centered design (UCD) adoption issues in development, overall assessment of usability/UCD in Korea, and the most widely used methods and techniques. The results of this study are expected to provide an empirical basis for usability and UCD planning, training, adoption and execution in IT industry of Korea.

This research dealt with feasibility study to build a route guidance robot for a blind man. It is important to recognize user's intentions for the guidance robot. The user's intentions have been caught through the information from joystick which has been processed by fuzz logic. We show that mobile robot obeys according to the recognized user's intention.

Lately Construction industry tends to prefer remodeling of existing building rather then new construction or reconstruction of buildings due to strengthening of several restriction related to real estates along with prolonged depression. Specially in case of Apartment houses, since vagueness on ownership and management authority on common part exists. So in this study we are to present the procedure of analyzing apartment house remodeling method through user request by approaching to several considerable factors in user request side.

For the effective use of information in the information society, information should be protected and outflow of information by illegal users should be prevented. This study sets up user authentication policy, user authentication regulations and procedures for information protection and builds information protection key distribution center and encryption user Authentication system, which can protect information from illegal users.
